With write root ...\out, a save to ...\out\x.svg:evil was accepted: it stays inside the root, but writes a hidden stream no folder listing shows. A ':' in any name after the drive is now refused with the device names. The check is a plain name test, so it is covered on every platform; the check-then-open race (item 1 of the report) is a documented limitation and is not touched.
The canvas keeps a hairline visible by raising a stroke's weight to half a device pixel. A width profile multiplies that weight, so a 1 pt stroke with a 6x width point swelled to twice its size at 25% zoom and shrank back on zooming in. The minimum now goes to the profile's widest point instead; plain strokes are unchanged.
The grid options' public page lists a Preview option: the repeat on the canvas follows the fields while the dialog is open. Object > Repeat > Options had none, so a change showed only after OK. Now a Grid Repeat's dialog has the checkbox: Cancel puts the original back without a history step, OK keeps the previewed values as one undo step. Radial and Mirror Repeat Options are left as they are, since their public pages list no Preview.
A mesh read from a file can have any number of patches, and the view any zoom: a 150 x 150 mesh from a 3 MB file exported at 20x asked for about 23 million quads (2 GB), and the command's own cap of 50 rows and columns does not apply to a loaded one. One tessellation now makes at most 1,048,576 quads, the subdivision per patch giving way before that, and a mesh with more patches than that is malformed, like a point count that does not fit.
When the conjugate a ∘ self ∘ a⁻¹ overflows, conjugated now forms every
entry of the product as a sum of terms whose factors are split into a
mantissa and a power of two, and scales the whole product by one power of
two from its w row at the end. Scaling each partial product to a largest
entry of 1 could round an entry to 0 that the next factor would restore,
so a projection with entries far apart in size, such as a scale by
(1e160, 1e-160) seen through the same scale, was removed and the art drew
flat.
The move drag remembers the plane it places loose art on. Pressing 4
during the drag, or dragging on after it, previews and commits the move
on that plane instead of dropping it. A 1-3 key pressed before the drag
threshold also sets the plane the move uses.
library_file_name kept CON, NUL, COM1 and the like, which Windows treats as
devices, not files. It now adds a - after such a name (CON-.json).
Part of #3602
Each patch of a gradient mesh was cut into 8 x 8 flat quads for SVG export,
Object > Expand and the other outputs that cannot shade a mesh, whatever its
colours, so a patch of one colour became 64 identical pieces. Neighbouring
quads are now joined into square blocks wherever the colour changes by no
more than about one 8-bit step across the block; the block's outline runs
through its quads' corners, and a patch that folds over itself is not joined.
The Bosnian catalog still carried the Color (,) and Gradient (.) rows, which no longer match the toolbar's tips. It now translates Color (, or Shift+,) and Gradient (. or Shift+.) like the other catalogs.
When the conjugate of a projection overflows, it is now formed one factor
at a time, and each partial product is divided by its largest entry
magnitude. Scaling the affine factors up front let the w row underflow to
0, so a scale by 2 seen through a move by 1e308 returned None and the
projection was removed, though its conjugate is finite.
perspective.move takes constrain: true instead of a plane-space
direction. For each object, the command snaps the move to the nearest
axis or 45-degree diagonal of that object's own plane, so a selection on
several planes keeps every object on a line of its plane. The tool sends
the raw pointer with the flag.
On a diagonal, Snap to Grid now moves along the diagonal by the nearer
per-axis correction, so that edge lands on its gridline.
When conjugating a projection overflows, the scaled-down result is now divided by the largest entry in its w row. A valid conjugate is no longer dropped by the determinant cutoff at the arbitrary scale, and every point of a kept projection passes the horizon test in apply instead of none.
perspective.move takes an optional constrain: [dx, dy], a plane-space
direction. For an in-plane move, Snap to Grid's correction is projected
onto that direction, so a move the Shift key constrains to a plane axis
or a 45-degree diagonal stays on that line when an object edge lies near
a gridline. The Perspective Selection tool sends the direction for
Shift moves and copies. Moves without the param behave as before.
